Choosing a lighting option goes beyond brightness levels; it’s about technology innovation and efficiency, as well as design and practical application. Two types used in the industry today are COBs (Chip on Board) and regular LEDs. Both have their advantages for specific situations. This blog will list the pros and cons and specific applications where each one shines.

Exploring the Differences Between COBs and Standard LEDs

In the last few years since LED technology was introduced, traditional LED has become more efficient and durable while newer technologies like COB LEDs emerged. These two types of LEDs are often pitted against each other, sparking debates among buyers and industry experts when it comes to which is best for home and commercial lighting.

LED lighting is a long-term and expensive commitment so you must weigh the pros and cons of your options.

COB LED Technology Explained

COB means Chips on Board. This type of lighting uses multiple LED chips on one board, as the name says. This helps create a more intense light compared to other LED technologies. Here are its advantages:

• High Intensity: The COB LED technology produces one strong beam of light because it has the LED chips placed in very close proximity with each other which is denser than most other LED chip technologies. The arrangement of the chips results in a more focused and consistent light beam while decreasing glare and ensuring uniform brightness levels throughout.
• Energy saving: COBs are more efficient than others because of high lumens per watt. This means they can produce the same level of light intensity using less power.
• Reliability: The multiple LED chips will spread the light evenly and with no harsh shadows. This increases the efficiency of the production of light and the overall quality of light produced.
• Superior Heat Dissipation: The compact design of COB LED chips tends to generate more heat than if the chips are installed in an array as is the case with other LED lamps. Nevertheless, designers were able to manage this by working with a thermal substrate that served as the primary way to control temperature.

Traditional LED Technology Explained

A light-emitting diode (LED) is simply a diode that illuminates when an electric current passes through it. Red, green, and blue diodes form each LED chip, in turn, are located in sequence on a printed circuit board (PCB). For general lighting applications like street lamps and home lighting, regular LEDs are used. They’re also used in applications that need a wide array of colors and light effects. Here are its advantages:

• Modular Design: Traditional LEDs come as chips that can be mounted individually or combined with components for different lighting setups offering flexibility in design and configuration options.
• Versatility: Traditional LEDs come in various types, including the popular SMD (Surface Mounted Device), which offers different brightness levels, wide color options, and beam angles. This versatility allows traditional LEDs to be used for decorative or general-purpose lighting needs.
• Longer Life: Depending on usage and brand, COBs are designed to last up to 60,000 hours. The long lifespan means you save up on any additional maintenance and replacement costs.
• Cheaper: Because they’re an older technology and production has been streamlined, traditional LEDs are cheaper than the newer and more advanced COBs. Typical LEDs are perfect for larger installations or projects operating with a limited budget. Modern conventional LEDs can help you save on energy—and money—compared to outdated lighting options such as incandescent or halogen bulbs.

COB LED vs LED Comparison

Design

COB LED:

• Compact Design: COB LED chips are packed tightly to minimize gaps between them. This reduces the “dead” space and increases the light intensity of COBs, good for applications that require consistent and even brightness.
• Consistent Light Distribution: The light beam from COB LEDs is even. This uniformity is beneficial in applications that require consistent light coverage such as retail displays, art galleries, and large office spaces. The fewer shadows and hotspots make the light quality and visual appeal better.
• Integration: COB LEDs integrate multiple chips into a single module, simplifying the assembly process and reducing the number of individual components. This integration not only simplifies manufacturing but also improves reliability and consistency in performance. Fewer components mean less chance of individual failures affecting the entire setup.

Traditional LED Design:

• Individual Placement: Traditional LEDs also known as SMD (Surface-Mount Device) LEDs are mounted separately on a circuit board. Individual placement means there’s a gap between each diode so there can be uneven light output in some applications. This is appropriate for applications that need flexibility and adaptability, even though it might not offer as much continuous lighting as COB LEDs.
• Dispersed Light Output: Gaps between diodes in traditional LED design can cause less uniform light output. While LED technology has improved this, light distribution may still vary especially in applications that need high consistency.
• Modularity: Traditional LEDs can be replaced individually, so maintenance and customization are easier. This modularity is good for applications that need periodic updates or repairs as individual LEDs can be replaced without replacing the whole display.

Winner: COB LEDs. In applications requiring seamless and high-density illumination, COB LEDs’ small size and consistent light output make them superior to conventional LEDs.

Brightness

COB LED Brightness:

• Increased Brightness: Because COB LED chips are smaller than traditional LEDs, they provide more light. This is good for applications that need high lighting such as large commercial spaces, high-visibility signage, and stadium lighting.
• Efficiency: COB LEDs generate a lot of lumens while using less electricity. Low power consumption means lower operational costs.
• Beam Angle: COBs have a wider beam angle so light distribution is quite broad. This is good for places like warehouses, exhibition venues, and open workspaces where wide lighting is needed.

Traditional LED Brightness:

• Medium Brightness: Although traditional LEDs are more energy efficient than COBs, their brightness output is lower. The dispersed diodes of traditional LEDs may not produce the same level of brightness, especially in demanding situations.
• Efficiency: Efficiency-wise, traditional LEDs have decent light output in some scenarios. But not as strong as COB LEDs. Although this is the case, it’s still a viable option for many lighting needs because of the balance of performance and cost.
• Beam Angle: Traditional LEDs have a narrower beam angle, which can result in less uniform light distribution. This can be addressed by using reflectors or lenses but may not always provide the same level of broad coverage.

Winner: COBs can produce brighter lights more efficiently than standard LEDs.

Shape

COB LED Size & Shape:

• Compact: COBs are perfect for areas with limited space because of their small size and high output.

Traditional LED Size & Shape:

• Bigger Size: From a size and intensity perspective, COBs are bigger and less concentrated than traditional LEDs. This limits its application in compact spaces where more integrated solutions are needed. A bigger size means bigger fixtures or housing.
• Less Flexible: The bigger form factor of traditional LEDs can limit its application in thin or flexible lighting solutions. This can affect its design and installation scenarios.
• Design Constraints: Traditional LEDs need more space on the circuit board which can reduce the number of diodes that can be included.

Winner: COBs are better for lighting in smaller working areas.

Traditional LEDs:

• Cheaper: Traditional LEDs are cheaper than COBs and good for budget-constrained projects.
• Lower Value for Money: Traditional LEDs have decent performance but are not as bright and long-lasting as COB LEDs. Their affordability makes them good for projects where performance isn’t a must.
• Consistent Prices: Since traditional LED technology is already established, their pricing is steady and affordable which makes it easier to compare one brand to another.

Winner: When it comes to cost, traditional LEDs have an advantage due to their affordability and stable pricing. But COBs have long-term benefits on ruggedness and performance.
